Exploration of Blunt Nose Cone with High Temperature Ceramic Composite TPS Materials

Aamer Sohail

Abstract


A new nose cone concept that promises a gain in performance over existingconventional nose cones is discussed in this paper the term nose cone is used to refer tothe forward most section of a rocket, guided missile or aircraft. The cone is shaped tooffer minimum aerodynamic resistance.In this study a natural nose cone with specific ultra-high Temperature (UHT) ceramic composite TPS materials like Hafnium diboride (HfB2) and zirconium diboride (ZrB2) is analyzed and when compared for its strong protection towards switch of warmness into the constitution. A naval model is designed for from the standards of blunt nose cone and analyzed with the commercial program. A normal quad 4 node aspects is adopted to participate in thermal evaluation in ANSYS program and the simulated outcomes are validated with numerical solutions. Present ablative materials like SLA-561V, SIRCA and AVCOAT are having the warmth flux levels up to an110W/cm2 and temperatures ranging as much as 2000˚C and want of recent substances and its reliability are focused in this research.
